Hey make sure that Catalina's comments have been resolved. I see things you haven't changed like the initial bar that appears before the authors or Jay's photo in the bios.

Hi Guillermo,

Sorry for not getting back to you, it has been super hectic in the last weeks.

Right now I am at a summer school but next week I will adress all the remaining points.

I can't get the demo to display, can you see it?

[Exferro]

Hm, I can't see it too, maybe @davidecast has more info?

[josh146]

That is very strange 🤔 It is available here (https://qml-build-previews.pennylane.ai/pull_request_build_preview/535/demos/tutorial_qpe.html), but not sure why it is not showing up on the chemistry page

[davidecast]

Not sure why this is happening, I only accepted some comments from Catalina and added my picture to the bio. I'll try to look a bit into it during the afternoon :/

[KetpuntoG]

@josh146 same problem in this other demo. It was finished but now does not display in the chemistry page 🤔

[josh146]

It looks like both demos are out of sync with the master branch :) If you look at the demos_*.rst files, they should be using .. gallery-item::, not .. customgalleryitem::

https://github.com/PennyLaneAI/qml/blob/master/demos_quantum-chemistry.rst

[KetpuntoG]

Oh thank you! That was the problem! 😍 I thought that as long as the PR didn't say that the branch was out of date, it would be the synchronization

[KetpuntoG]

I learned a lot from this demo! 💯 But to be production-quality, it still needs several changes:

• There's an incomplete section
• Typos and grammar, acronyms
• Some parts require more explanation. Mostly the initial QPE code, the use of QPE after VQE.
• Code needs more comments

Please do not click on resolve conversation in any of the comments. Only reviewers will do this. If you need to implement a suggestion, click on commit suggestion. And if you've already fixed some of these locally, please don't forget to push the latest version as you do!

@Exferro @davidecast , could you work on the requested changes? Remark again, you will have to click on commit suggestion if you accept the change :)

[Exferro]

Hey @KetpuntoG! I know, this is long overdue, but I got buried under lots of academic/teaching obligations, I will get back to this demo when the Oxford term is over, i.e. on the week starting December 5.

Sorry for keeping postponing!

[KetpuntoG]

Let's try to finish this soon in January :)

[KetpuntoG]

@Exferro @davidecast please do not leave this

[davidecast]

Hi @KetpuntoG!

Sorry for replying late and that we are dragging our last fixes, I will work on the remaining changes requested in the next days and then @Exferro will go on from there.

[KetpuntoG]

A new QPE demo with the new PL features is on the way. I close this PR as it is not expected to be merged
